Recipe Notes:

  1. Don’t overcook the steak: When browning the steak cubes in the skillet, remember that they don’t need to be fully cooked through. Browning them on all sides will help seal in the juices and add extra flavor.
  2. Adjust the seasoning to your taste: The Montreal Steak seasoning blend provides a delicious flavor profile, but feel free to adjust the amount of seasoning and salt to suit your preferences.
  3. Use baby red potatoes: Baby red potatoes are ideal for this recipe because they hold their shape well and have a creamy texture when cooked. If you can’t find baby red potatoes, you can use other waxy potatoes like Yukon Gold or fingerling potatoes.
  4. Experiment with cheese: While the recipe suggests using shredded sharp cheddar cheese, you can get creative and try different cheese varieties. Gouda, Swiss, or a combination of different cheeses can add unique flavors to the casserole.
  5. Tent with foil if necessary: If you notice the cheese on top of the casserole is browning too quickly, you can tent it with aluminum foil to prevent it from burning. Keep an eye on the casserole during the baking process to ensure it cooks evenly.

Can I use a different cut of meat for this recipe?

While the recipe calls for London Broil steak, you can certainly use other cuts such as sirloin or ribeye. Just make sure to cut the meat into bite-sized cubes for even cooking.

Can I substitute the cream of mushroom soup with another soup?

If you’re not a fan of cream of mushroom soup, you can try using cream of chicken or cream of celery soup as alternatives. The choice of soup will slightly alter the flavor, but it will still be delicious.

Can I make this casserole ahead of time?

Absolutely! You can prepare the casserole ahead of time and refrigerate it until you’re ready to bake. Just cover it tightly with plastic wrap or aluminum foil and store it in the refrigerator for up to 24 hours. When ready to bake, remove it from the refrigerator, let it sit at room temperature for about 30 minutes, and then follow the baking instructions.

    This was very good! Hubs said to make it again, he’s a meat and potatoes kind of guy. I did make a couple mods, I did buy the London broil, but on the rest I used what I had. I subbed Yukon gold for the reds and cream of celery for the mushroom. My potatoes weren’t baby and perhaps I cut them larger that what the recipe instructed because my dish was cooked in 90mins. I did opt to top with the cheese at the end, which allowed me to stir it halfway, and I also deglazed my frypan with a little red wine. I feel the dish needs color, perhaps a carrot? I could also see some bacon in this. But on the whole, even though it was summer, it reminded me of good old fashioned chuck wagon type food. Yum! Hubs is still talking about it =)
